Industrial coating thickness and coating weight measurement systems are used to monitor coating uniformity, basis weight, and coating density across many manufacturing processes. These systems are commonly installed on battery electrode coating lines, roll-to-roll coating systems, semiconductor wafer processes, and powder coating production lines. Non-contact technologies including X-ray, photothermal, confocal, and ultrasonic measurement allow engineers to measure coating thickness and coating weight in real time.
Gauge Advisor is the official sales partner for AIM Systems and Scantech to deliver non-contact coating thickness and weight measurement and process-control solutions for advanced coatings. AIM’s photothermal gauges measure coating thickness and uniformity, while Scantech provides real-time coating weight and density data for high-precision adhesive, battery, and aerospace coating lines. These systems are used by manufacturers in the battery, semiconductor, packaging, aerospace, and medical device industries to control coating thickness, basis weight, and coating density during production.

Deploy high-speed thickness measurement directly on production lines via robotic arms or fixed-mount systems. Optimized for high-throughput environments, this non-contact approach provides real-time feedback on wet, uncured, or sensitive coatings without risk of surface damage or “recharge” downtime between measurements.
Capture comprehensive coating thickness data across defined surface areas using pre-programmed robot trajectories or measurement sequences. Generate high-resolution 2D heat maps with the CoatPro XD to identify coating variation, edge effects, and localized defects across complex geometries.
Validate coating performance during the R&D phase, process setup, and final quality audits. This non-destructive testing method is ideal for large assemblies, enclosed processes, or challenging materials where traditional contact-based gauges fail to provide repeatable data.
Measure with precision on concave, convex, or highly angled surfaces. The advanced optical design offers a high tolerance for part curvature and tilt (up to 70 degrees), ensuring reliable results on automotive components, battery trays, and intricate industrial hardware.
Engineered for industrial stability, this technology is highly tolerant to mechanical vibrations and component movement. Periodic LED excitation ensures stable measurement even in rigorous production environments where ambient temperature fluctuations might otherwise compromise accuracy.
Future-proof your quality control with seamless Industry 4.0 connectivity via Ethernet and Modbus TCP. Due to the low-power LED excitation, these systems are the only non-contact gauges suitable for fast inline measurement on wet coatings within Ex-Zone 1 and Zone 2 environments.
Scan across the entire moving web to measure coating thickness or basis weight in real-time. Detect cross-web variation, edge effects, and process drift before they impact product quality. Available in O-frame configurations with widths ranging from 0.5 meters – 15 meters
High-precision measurement of coating basis weight, thickness, and density on lithium-ion battery electrode lines. Specialized sensors provide high-resolution “bunny ears” profile visualization and 100% inspection of substrate, wet, and dry coating layers.
Proprietary X-ray transmission technology designed specifically for the hydrogen fuel cell market. This solution allows manufacturers to measure platinum (Pt) catalyst weight separately from the membrane , a critical requirement for controlling high-cost material usage in PEM and MEA production .
Specifically engineered for pilot lines, narrow-web converters, and tight machinery constraints. These ultra-compact O-frame and C-frame scanners provide full-scale measurement accuracy while requiring minimal installation space along the web path.
Eliminate measurement errors caused by substrate variation. Our advanced “Same Spot” technology synchronizes multiple scanners to measure the substrate and coating at the exact same lateral position , ensuring absolute thickness and weight accuracy for multi-layered materials.
Move beyond simple monitoring to automated regulation. Real-time measurement data feeds directly into the Auto Profile Control (APC) system, automatically adjusting thermal die bolts or line speeds to maintain perfect uniformity and reduce start-up waste.
Ensure corrosion protection and coating uniformity on complex automotive parts.

Different coating applications require different measurement technologies. Photothermal coating thickness measurement systems such as AIM CoatPro measure coating thickness on discrete parts, components, and engineered surfaces using non-contact optical methods. These systems can operate in spot measurement, multi-point mapping, or full area scanning modes depending on the inspection requirement.
For continuous roll-to-roll coating processes such as fuel cell catalyst coated membrane lines, lithium-ion battery anode and cathode coating lines, and composite prepreg impregnation lines, full-width web scanning systems from Scantech measure coating properties across the moving web. These scanners combine X-ray transmission web gauging, ultrasonic auto-calibration, and confocal thickness sensors to monitor basis weight, thickness, density, and profile data in real time during production.
